A Framework for Integrated Infrastructure Condition Assessment and Traffic Assignment

The Virginia Department of Transportation (VDOT) is responsible for more than 128,000 lane miles of roadway that need to be in a good state of repair. Pavement condition data are crucial in estimating the cost to achieve and sustain VDOT's pavement performance targets. VDOT also strives to reduce congestion on its road networks, implementing different traffic operation, control, and travel demand management strategies. While these strategies result in changes to travel demand distributions, road congestions, travel routes, and travel modes, and while the condition of the pavement is obviously related to the traffic loading, there is currently no decision-support tool that can be used to predict the impact of these different strategies on pavement conditions. This paper presents the first steps in implementing a framework of integrated pavement condition assessment and traffic assignment that is intended to be included in the final project decision-support tool. The authors illustrate the proposed framework and provide a proof-of-concept study in Northern Virginia. An optimization process is involved in selecting pavement treatment and a dynamic profiler is used to show the interaction of traffic volume and overall budget in the final performance measures.
